posixspawn

The power of posix_spawn in your shell.

Overview

This is a command-line utility that wraps the posix_spawn function, exposing the extra process spawning functionality to your shell. It even supports all of Apple's private API's, such as spawning a process with ASLR disabled.

Usage

Usage: posixspawn [options...] [--] [args...]

options:
  -f <flags> Pipe-delimited list of flags (see flags section below).
  -p <path>  Set the executable path separate from arg 0.
  -w         Wait for child process to complete before returning?

args:
  The remaining arguments are passed to the child process.

flags:
  The flags arguments is a pipe-delimited list of constants or integers.
  A flag can be a string constant, a base-16 string, or a base-10 string.
  The flag uses the short data type, with each flag a maximum 2 bytes.
  Example argument:
    "EXAMPLE_CONSTANT|0xF0|16"

    0x0001  POSIX_SPAWN_RESETIDS
